TECHNICAL FIELD

Embodiments described herein generally relate to processing of video data and in particular, to gesture masking in a video feed.

BACKGROUND

With advancements in gesture detection, usability of gestures in computing devices and applications will become ubiquitous. With some computing devices, gestures are meant as local input and not for remote consumption. In this regard, in instances of video conferencing or other remote communication scenarios, gestures that are meant as local input may be undesirable for participants in the video conference or the remote communication scenario.

DETAILED DESCRIPTION

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of some example embodiments. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details.

Disclosed herein are systems and methods that provide processing of video data and more specifically, gesture masking in a video feed. A device may be running a local application and monitoring a video teed for gestures, which may be used as input to the application (e.g., the gestures may be interpreted as commands or input and the application may act upon them). The device may also be running a video conference client using the video feed. To avoid confusing video conference participants, the gestures associated with the local application can be masked so that they are not visible to the conference participants. In instances when the gesture is not associated with the local application and it is associated with the video conference (e.g., the user is gesturing as part of the video conference), then the gestures may be left unmodified. In instances when the gestures are used as input to the local application as well as an input to the video conference client, then the gesture may also be left unmodified.

FIG. 1 is a diagram illustrating a video data processing system, according to an embodiment. Referring to FIG. 1, the video data processing system 100 may include a camera system interface 102, a gesture detection unit 104, a permission unit 106, and a video processor 108.

The camera system interface 102 may receive camera signal information from a camera array 112, which may be installed on the system 100 or be remote, but communicatively coupled to the system 100. For instance, the camera system interface 102 may receive raw video signal information or processed signal information (e.g., compressed video signals). In another aspect, the camera system interface 102 may be used to receive video data from a buffer 114, which may be remote from the system 100 or may be included as part of the system 100. The camera array 112 may be a depth camera, an infrared camera, visible light camera, or another type of camera. Further, the camera array 112 may include multiple types of cameras, which may work in concert with each other or may be bundled into the same optical capture system.

The gesture detection unit 104 may comprise suitable circuitry, logic and/or code and is capable of analyzing image or video data received by the camera system interface 102, and detect and identify a gesture exhibited by movements performed by a person in the image or video data (e.g., a user of a device incorporating the system 100). The gesture detection unit 104 determines whether the movements constitute a recognized gesture (e.g., by using machine learning). If the movements do constitute a recognized gesture, the gesture detection unit 104 may provide the recognized gesture to the permission unit 106 and the video processor 108 for further processing.

To detect the gesture, the gesture detection unit 104 may access a gesture database 130. The gesture detection unit 104 accesses image data of a movement (e.g., movement of an arm, finger, foot, or hand motion) of a user captured by the camera array 112 and received via the camera system interface 102. The gesture detection unit 104 then identifies the gesture (e.g., gesture 110) from the gesture database 130 based on the image data. The image data may be a number of successive images (e.g., video) over which the gesture 110 is performed.

In another aspect, the gesture detection unit 104 accesses depth image data of an arm, finger, foot, or hand motion of a user captured by the camera array 112, and identifies the gesture (e.g., gesture 110) from the gesture database 130 based on the depth image data. The depth image data may be a number of successive images (e.g., video) over which the gesture 110 is performed.

In an example, the gesture database 130 may be organized based on applications (or apps) that may use gestures (e.g., as inputs). More specifically, the available gestures in database 130 may be organized as gestures 132, . . . , 134 associated with apps 1, . . . , N, respectively. The apps 1, . . . , N may be applications running locally (e.g., on the device implementing the system 100) as well as remote applications (e.g., remote conference clients) running remotely from the device. The gesture database 130 may also include information indicating whether the apps 1, . . . , N allows a corresponding gesture to be displayed (e.g., if a gesture is used as an input to an application, then the application may not allow that gesture to be displayed within a video feed).

In another aspect, the gesture detection unit 104 operates independent from the camera system interface 102, and receives information or data that indicates a gesture via a different pathway. For example, in an aspect, to detect the selection gesture, the gesture detection unit 104 is to access motion data from an auxiliary device, the motion data describing an arm, finger, foot, or hand motion of the user and identify the gesture based on the motion data. The auxiliary device may be a mobile device, such as a smartphone, a wearable device, such as a smartwatch or a glove, or other type of device moveable by the user in free space. Examples include, but are not limited to, smartphones, smartwatches, e-textiles (e.g., shirts, gloves, pants, shoes, etc.), smart bracelets, smart rings, or the like.

The permission unit 106 may comprise suitable circuitry, logic, and/or code and is capable of determining a masking permission associated with the detected gesture. The masking permission may indicate (e.g., to the video processor 108) whether the detected gesture is to be modified or left unmodified. In an example, the permission unit 106 may access the gesture database 130 and identify whether the gesture is associated with an application that allows gestures to be displayed. Optionally, the gesture detection unit 104 may provide information identifying the gesture (e.g., 110) as well as an application (or applications) associated with the gesture. The gesture detection unit 104 may also provide information indicating whether the application associated with the gesture allows the gesture to be displayed. The permission unit 106 may generate the masking permission based on whether the gesture may be displayed.

In another aspect, the permission unit 106 may access a user preference database 140 to determine a user preference associated with the detected gesture 110. The user preference database 140 may be a user-specific database associated with an account of a user of the system 100, where the user may set up specific masking permissions for certain gestures.

The user preference may indicate whether the gesture is to be modified when displayed, based on the application (or applications) it is associated with. For example, a paging gesture with one hand may be an input gesture for changing pages within a local word-processing app running on the device with system 100. The user preference for this gesture may indicate that the gesture is to be modified within a video feed with the gesture, since the gesture is associated with a local application running on the device.

In another example, the same paging gesture may be used locally by the word-processing app but may also be used by a remote app, such as a remote video conferencing client 120. The remote video conferencing client 120 may be used for video conferencing between a user of the device using the processing system 100 and another user. In this case, since the same gesture may be used locally as well as by the remote client, the user preference may indicate that the gesture is to be unmodified within the video feed.

In yet another example, the paging gesture may be associated only with the remote video conferencing client 120. In this case, the user preference may indicate that the gesture is to be unmodified since it is only being used by the video conferencing client 120. The user preference database 140 may also indicate a universal masking permission when a gesture is not found within the gesture database 130 (e.g., mask any gesture that is not within the database 130).

The video processor 108 may comprise suitable circuitry, logic, and/or code and is capable of performing gesture modification in connection with a detected gesture 110. Incoming video data from camera array 112 may be communicated to both the video data processing system 100 and the video stream buffer 115. After the gesture 110 is identified and the masking permission for the gesture is determined, the video processor 108 may perform gesture modification 111 in connection with the masking permission determined by the permission unit 106. More specifically, the video processor 108 may obtain pixel coordinates associated with the gesture 110 (e.g., from the gesture detection unit 104). The pixel coordinates of the gesture may be used by the video processor 108 to access the video data within the buffer 115 and modify one or more video frames that include the gesture.

The gesture modification may include masking (censoring) the pixel region of the gesture within one or more video frames (e.g., placing a black box mask or another type of mask or blur within the pixel region of the gesture). Alternative gesture modifications may include removing the frames containing the gesture from the video feed, or replacing the frames containing the gesture with frames (e.g., previous frames) that do not contain the gesture. The modified video data from the video stream buffer may be encoded by video encoder 116, and may be communicated to a local video conference client 118 or to a remote video conference client 120 (via the network 122).

The camera system interface 102, gesture detection unit 104, permission unit 106, and video processor 108 are understood to encompass tangible entities that are physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operations described herein. Such tangible entitles may be constructed using one or more circuits, such as with dedicated hardware (e.g., field programmable gate arrays (FPGAs), logic gates, graphics processing unit (GPU), a digital signal processor (DSP), etc.). As such, the tangible entities described herein may be referred to as circuits, circuitry, processor units, subsystems, or the like.

Even though the databases 13 and 140, as well as the video encoder 116, are illustrated separately from the video data processing system 100, the present disclosure may not be limited in this regard. The database 130, database 140, the video encoder 116 and/or the buffer 115 may be included as part of the system 100.

FIG. 2A illustrates an example gesture that has been detected by the video data processing system, according to an embodiment. Referring to FIG. 2A, the user 200 may be performing gestures during a video conference. The gesture detection unit 104 may detect hand gestures 202 and 204, and may determine that the gestures 202 and 204 are used as inputs for a word-processing application running on a device used by the user 200. The permission unit 106 may determine the masking permission for the gestures 202 and 204, which may indicate that the word-processing application does not allow display of the gestures, and the gestures have to be masked.

FIG. 2B illustrates masking of the gesture detected in FIG. 2A, according to an embodiment. Referring to FIG. 2B, the video processor 108 may perform gesture modification based on the masking permission determined by the permission unit 106. Since gestures 202 and 204 are associated with an application that does not allow display of gestures, the video processor performs gesture modification by placing a mask 206 over gestures 202 and 204.

FIG. 3 and FIG. 4 are flowcharts illustrating example methods for processing of video data, according to an embodiment. Referring to FIG. 1 and FIG. 3, the example method 300 may start at 302, when an input video feed is received (e.g., via the camera array 112 and the camera system interface 102). At 304, the gesture detection unit 104 may determine whether a gesture is present within the video feed. If a gesture is not present, then the video encoder 116 encodes the video stream, and the encoded stream may be output at 312 (e.g., to a remote video conference client 120).

If a gesture is present, then at 308, it may be determined whether there is a local system response to the gesture. More specifically, it may be determined whether the detected gesture is an input to a local application (or is otherwise used by a local application). If there is no local system response to the gesture (e.g., the gesture is not used by the local application), then the video stream is output at 312. If there is a local system response to the gesture (i.e., the gesture is used by the local application), then at 308, the gesture detection unit 104 may identify the gesture coordinates (e.g., pixel coordinates in one or more frames containing the gesture) At 310, the video processor modifies the gesture (e.g., conceal or replace the gesture in the video feed stored in buffer 115) using the pixel coordinates of the gesture. After gesture modification, the video encoder 116 may encode the stream for output to the conference client 118 and/or 120.

Referring to FIG. 1 and FIG. 4, the example method 400 may start at block 402, when video data is received from a camera system. At block 404, a gesture is determined within the video data, where the gesture may be performed by a user. At block 406, a masking permission may be determined where the masking permission may be associated with the detected gesture. At block 408, a portion of the video data associated with the gesture may be modified in accordance with the masking permission. At block 410, the portion of the video data may be displayed.

In an embodiment, determining of the gesture includes accessing a gesture database with available gestures to determine a match. The gesture may be any type of gesture, as discussed above, and may include actions such as pointing, waving hands, or other similar gestures. Additionally, determining of the gesture may include determining an application that is associated with the gesture (e.g., the application uses the gesture as a command or input).

In an embodiment, determining the masking permission may include accessing a user preferences database to determine a user preference associated with the gesture. The user preference can indicate whether the gesture is to be modified when displayed. For example, the user preference can indicate that the gesture is to be modified when the gesture is associated with a local application running on the video processing system (e.g., the gesture is used by the local application but it is not needed for a video conference client using the video feed).

In an embodiment, modifying the portion of the video data associated with the gesture includes replacing or obscuring the gesture based on the masking permission. Replacing the gesture may include accessing a buffer to obtain a previously displayed frame from the video data, and displaying the previously displayed frame as a replacement to a video frame with the gesture.

Embodiments may be implemented in one or a combination of hardware, firmware, and software. Embodiments may also be implemented as instructions stored on a machine-readable storage device, which may be read and executed by at least one processor to perform the operations described herein. A machine-readable storage device may include any non-transitory mechanism for storing information in a form readable by a machine (e.g., a computer). For example, a machine-readable storage device may include read-only memory (ROM), random-access memory (RAM), magnetic disk storage media, optical storage media, flash-memory devices, and other storage devices and media.

A processor subsystem may be used to execute the instruction on the machine-readable medium. The processor subsystem may include one or more processors, each with one or more cores. Additionally, the processor subsystem may be disposed on one or more physical devices. The processor subsystem may include one or more specialized processors, such as a graphics processing unit (GPU), a digital signal processor (DSP), a field programmable gate array (FPGA), or a fixed function processor.

Examples, as described herein, may include, or may operate on, logic or a number of components, modules, or mechanisms. Modules may be hardware, software, or firmware communicatively coupled to one or more processors in order to carry out the operations described herein. Modules may be hardware modules, and as such modules may be considered tangible entities capable of performing specified operations and may be configured or arranged in a certain manner. In an example, circuits may be arranged (e.g., internally or with respect to external entities such as other circuits) in a specified manner as a module. In an example, the whole or part of one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware processors may be configured by firmware or software (e.g., instructions, an application portion, or an application) as a module that operates to perform specified operations. In an example, the software may reside on a machine-readable medium. In an example, the software, when executed by the underlying hardware of the module, causes the hardware to perform the specified operations. Accordingly, the term hardware module is understood to encompass a tangible entity, be that an entity that is physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operation described herein. Considering examples in which modules are temporarily configured, each of the modules need not be instantiated at any one moment in time. For example, where the modules comprise a general-purpose hardware processor configured using software; the general-purpose hardware processor may be configured as respective different modules at different times. Software may accordingly configure a hardware processor, for example, to constitute a particular module at one instance of time and to constitute a different module at a different instance of time. Modules may also be software or firmware modules, which operate to perform the methodologies described herein.

Circuitry or circuits, as used in this document, may comprise, for example, singly or in any combination, hardwired circuitry, programmable circuitry such as computer processors comprising one or more individual instruction processing cores, state machine circuitry, and/or firmware that stores instructions executed by programmable circuitry. The circuits, circuitry, or modules may, collectively or individually, be embodied as circuitry that forms part of a larger system, for example, an integrated circuit (IC), system on-chip (SoC), desktop computers, laptop computers, tablet computers, servers, smart phones, etc.

The computer system 500 may further include a video display unit 510, an alphanumeric input device 512 (e.g., a keyboard), and a user interface (UI) navigation device 514 (e.g., a mouse). In one embodiment, the video display unit 510, input device 512 and UI navigation device 514 are incorporated into a touch screen display. The computer system 500 may additionally include a storage device 516 (e.g., a drive unit), a signal generation device 518 (e.g., a speaker), a network interface device 520, and one or more sensors (not shown), such as a global positioning system (GPS) sensor, compass, accelerometer, pyrometer, magnetometer, or other sensor.

The storage device 516 includes a machine-readable medium 522 on which is stored one or more sets of data structures and instructions 524 (e.g., software) embodying or utilized by any one or more of the methodologies or functions described herein. The instructions 524 may also reside, completely or at least partially, within the main memory 504, static memory 506, and/or within the processor 502 during execution thereof by the computer system 500, with the main memory 504, static memory 506, and the processor 502 also constituting machine-readable media.

While the machine-readable medium 522 is illustrated in an example embodiment to be a single medium, the term “machine-readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more instructions 524. The term “machine-readable medium” shall also be taken to include any tangible medium that is capable of storing, encoding or carrying instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present disclosure or that is capable of storing, encoding or carrying data structures utilized by or associated with such instructions. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media. Specific examples of machine-readable media include non-volatile memory, including but not limited to, by way of example, semiconductor memory devices (e.g., electrically programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM)) and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

The instructions 524 may further be transmitted or received over a communications network 526 using a transmission medium via the network interface device 520 utilizing any one of a number of well-known transfer protocols (e.g., HTTP). Examples of communication networks include a local area network (LAN), a wide area network (WAN), the Internet, mobile telephone networks, plain old telephone (POTS) networks, and wireless data networks (e.g., Bluetooth, Wi-Fi, 3G, and 4G LTE/LTE-A or WiMAX networks). The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible medium to facilitate communication of such software.
